After discussing plans to leave New York with Kourtney, the reality star gets emotional as she tries to grapple with her lack of connection to her then-husband Kris Humphries, a man who she says is "everything on paper [she] wants."

"I invited all these people to this huge wedding and flew everyone out, wasted everyone's time and everyone's money -- everyone's everything -- and I feel bad!" she says. "At 30 years old, I thought I'd be married with kids and I'm not. I failed at this. People change their minds, people make mistakes."
